A Papillary Fibroelastoma Involving Aortic and Pulmonary Valves: Findings on Multimodality Imaging.

Cardiac papillary fibroelastoma, a rare entity, is the second most common benign primary cardiac tumor. Commonly involving the cardiac valves, this entity is increasingly diagnosed using different imaging modalities. We present a rare case of simultaneous involvement of both the aortic and pulmonary valves in an asymptomatic patient who underwent different imaging modalities, including transthoracic and transesophageal echocardiography, nongated and gated computed tomography, and magnetic resonance imaging.

Cardiac MRI and Ischemic Heart Disease: Role in Diagnosis and Risk Stratification.

Cardiac magnetic resonance imaging (CMRI) has been under development for the past four decades and has more recently become an essential tool in the evaluation of ischemic heart disease (IHD). It is the reference standard for quantification of both right and left ventricular volume and function and, after landmark work published in the New England Journal of Medicine in 2000, has proven effective in identifying hibernating myocardium, or hypokinetic myocardium that will recover after revascularization. More recent literature continues to support both delayed enhancement imaging and CMRI stress perfusion as essential tools in evaluating IHD.

Glioblastoma: a method for predicting response to antiangiogenic chemotherapy by using MR perfusion imaging--pilot study.

Purpose: To derive a magnetic resonance (MR)-based imaging metric that reflects local perfusion changes resulting from the administration of angiogenic-inhibiting chemotherapy in patients with recurrent glioblastoma multiforme (GBM).

Materials And Methods: In this retrospective Institutional Review Board-approved HIPAA-compliant study, 16 patients (12 men, four women; mean age, 51.8 years + or - 15.
